Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532410, here are decompositions:

71 + 31532339 = 31532410
131 + 31532279 = 31532410
149 + 31532261 = 31532410
191 + 31532219 = 31532410
269 + 31532141 = 31532410
293 + 31532117 = 31532410
347 + 31532063 = 31532410
389 + 31532021 = 31532410

Showing the first eight; more decompositions exist.
